Now that some data exists, it's time to make sense of it in the form of
a graph. The inclued extension includes a PHP file named
gengraph.php that creates a dot file that
requires the » graphviz library.
However, this form is not required.

Example #2 Example use of gengraph.php

This example creates an image named inclued.png that
shows the inclued data.

Note that inclued does not work correctly when xdebug is enabled (the includes array remains empty; consequently, graphing the classes works but graphing the files does not). Bug report: https://bugs.php.net/bug.php?id=59419
